DC / DC converters as DC circuit-breakers in HVDC networks operation [PDF]
2014 16th European Conference on Power Electronics and Applications, 2014 This paper presents the modeling and control of a DC/DC bidirectional converter suitable for medium voltage and power applications in Multi-Terminals HVDC (MT-HVDC) grids. Moreover its use as DC circuit-breaker is described. This is a new concept, against the contemporary studies of DC breakers, which could help for the implementation of MT-HVDC ...
